It is true that some servers will not accept mail if the hostname used
by your mail server, mail.ecsi.net, does not match the hostname in the
PTR record for your IP address.

mail.ecsi.net does not match ATHM-209-125-xxx-3.home.net.

mail.ecsi.net.
    209.125.3.3

3.3.125.209.in-addr.arpa.
    host = ATHM-209-125-xxx-3.home.net.
